Possibly prego?

I'm under a lot of stress. I'm 9 dpo and yesterday I had nausea and got sick once. Now today my so and I have had a fight. I'm feeling so nauseous. I'm angry. And all I really want to do is scream, cry, and go to bed. But as a mother, that isn't possible to do. Just wondering if maybe I'm prego.. I had a very creamy discharge earlier before our fight. I just don't know what to do..
